Chiefy Posted July 20, 2007 Share Posted July 20, 2007 Hiya, I have been asked to look into putting together a portable induction loop system to be used for various events in and around our new centre. It must be able to pick up ambient noise as well as a direct input ie. music. I have hired the Vocaleyes sennhizer system before for various events which works great but is a little cumbersome in size...Has anyone had any experience of these systems? Can anyone recommend a good quality one that is not too large in the processing/psu end of things? Does anyone know of any companies who specialise in these systems, Ampetronic don't recommend their systems to be used as a portable system...

Simon Lewis Posted July 20, 2007 Share Posted July 20, 2007 Hi, Chiefy, Could we ask for a few more details? If the induction loop system is to be portable, does it have to work on the move, or be moveable to several different locations? If it's the latter, would this do the job? If the loop is for those with hearing loss, is there a particular reason for picking up ambient sound? There is often a provision for this to let the user know the system is "on", but the hearing aid user needs to hear the actual source without ambient noise if it is to help them hear clearly. The Sennheiser system is an Infra Red system. It is different from the loop, and has a number of advantages, but some disadvantatges too. If you can give some more information, then I'm sure we will be able to help you further. Simon Link to comment Share on other sites More sharing options...
Chiefy Posted July 20, 2007 Author Share Posted July 20, 2007 Hiya Simon, Thanks for your reply and in answer to your questions; No the system does not have to be used on the move, think of it to be used in conference, meeting situations for the hard of hearing or on a small show or event for sound re enforcement, or maybe even audio description. I have used the Sennheiser system before with the IR induction loops worn around the neck, which I have to say does not always work as they have a very small inductive loop range... I have heard of a radio system that again you have to wear a receiver pack for your hearing aid to pick up, but I cant seem to find any info about these systems...

Simon Lewis Posted July 20, 2007 Share Posted July 20, 2007 I think you may be slightly confused... The neck loop of the infra red receiver couples with the hearing aid magnetically. If it's working (i.e. signal is being sent to the hearing aid via the neck loop) then there isn't much that can go wrong - the loop is very close to the receiver. It would be unusual if the neck loop didn't provide sufficient signal. If however, you are findng that the signal from the IR transmitter to the IR receiver is problematic, then there is a problem with the infra red system. Could you explain which it is? Regarding the radio system, Williams Sounds do them, and you can use systems like Sennheiser radio Tourguide. Many of these are based on headphones, but I believe neck loops are available.

Chiefy Posted July 23, 2007 Author Share Posted July 23, 2007 Thanks Simon, I have used the IR systems for quite a few years now so I am quite versed to their problems, the main one being the radiator contact with the heads sets, particularly when the person using the head set/neck loop and is sat in an audience with the fob hanging down with the tallest person in the world is sitting in front!! The radio versions seem the way forward for the type of system I am looking for, I will check your links out and let you know, thanks again!
